Discover Arthrosamid®: A New Approach to Knee Osteoarthritis Relief

What Is Arthrosamid®?

Arthrosamid® is an innovative injectable treatment designed specifically for people with knee osteoarthritis. Unlike traditional options, this treatment uses a non-biodegradable hydrogel to create a cushioning layer within the joint. It works by enhancing lubrication and reducing inflammation — helping to ease pain and improve movement.


How Does Arthrosamid® Work?

Once injected into the knee joint, Arthrosamid® gets to work by:

  • Cushioning the joint, reducing pressure and impact

  • Improving joint lubrication, supporting smoother movement

  • Integrating with the soft tissue, becoming part of the synovial lining for long-lasting effect

This treatment is unique in that it doesn’t wear off quickly — it becomes part of your joint structure, delivering relief for up to four years, as demonstrated in clinical studies.


Key Benefits of Arthrosamid®

Patients who receive Arthrosamid® often report a noticeable improvement in their daily life. Some of the key benefits include:

  • Significant and long-lasting pain relief (up to 4 years)

  • Reduced joint stiffness and increased flexibility

  • Better mobility and confidence in movement

  • Non-surgical, minimally invasive option

  • Single injection with no ongoing medication needed


Is Arthrosamid® Right for You?

Arthrosamid® is typically recommended for individuals with knee osteoarthritis who are seeking an alternative to ongoing medication or surgery. It can be a great option if:

  • You’re not getting enough relief from physiotherapy or over-the-counter treatments

  • You want to avoid or delay knee replacement surgery

  • You're looking for a non-invasive, long-lasting solution

Our team can assess your condition and help determine whether Arthrosamid® is the right fit.


What to Expect During Treatment

Arthrosamid® is administered as an intra-articular injection — meaning it’s delivered directly into the knee joint. Here’s what the process involves:

  1. Local anaesthetic is applied to numb the area and ensure comfort

  2. The hydrogel is carefully injected into the joint space

  3. You may feel some mild discomfort or swelling afterward, but this typically settles quickly

  4. Most patients return to light activity within a day or two

The procedure is quick, and no hospital stay is required.


Safety and Side Effects

Arthrosamid® has been shown to be safe in clinical studies. Most reported side effects are minor and temporary, including:

  • Mild pain or swelling at the injection site

  • Brief stiffness or tenderness in the joint

No serious adverse events have been linked to Arthrosamid® to date.
